Powder metallurgy bearing is mainly used in
general raw material powder by pressing, sintering, shaping, immersion process
made. Now the machines are mostly relatively high degree of automation.
Production is relatively large, most of the products can be formed at a time,
so the larger the better production. And now with the mold less than a few
words can do hundreds of thousands, more than one million words may do more
than. But die cost is relatively high, so the lot of small words will not be
done, and the time to replace the mold is long. Powder metallurgy oil bearing
(oil bearing) is a kind of porous alloy product containing lubricating oil.
When the shaft rotates, the friction between the shaft and the bearing of the
increased oil bearing temperature and pump function.
